MPEG4 (XVID) playback issues.

[Pihkal]

Hi,

i'm breaking my head about this xvid-playback issue so i finally started a thread about it.
Here's the problem (sorry about the bad picture quality):





This however doesn't happen all the time,it plays ok but then for a second or two i get the garbage images above and this repeats multiple times over the entire episode.

The problem always occurs,upnp-,samba-,usb-source...it doesn't make any difference.
I'm on the latest xbian-build (RC2 compiled yesterday) but the previous version also had this problem.
I'm using a 128MB/128MB memorysplit.

Any ideas?
